Commercial Vehicle Parts – OEM Surplus & Overstock
Dealer markups and long lead times shouldn't get in the way of keeping your trucks running. BB Overstock Parts stocks genuine surplus and overstock OEM parts for commercial trucks — semi trucks, vocational trucks, and heavy-duty fleet vehicles — from brands like Freightliner, Cummins, Volvo, Mack, International/Navistar, Kenworth, and Peterbilt.
Every part in our commercial vehicle inventory is genuine OEM or verified surplus — not remanufactured, not aftermarket unless clearly marked. Whether you're a fleet maintenance manager, an independent repair shop, or a truck owner working on your own rig, you'll find the parts you need here at prices that make sense.
Inventory is limited and constantly changing. When a part is gone, it may not come back. If you need help with a part number, cross-reference, or fitment question before ordering, reach out — our team knows these parts.
